Dalia Mogahed came to Cal Poly's campus Saturday preaching a message of unity, and the nearly 1,000 people who filled Chumash Auditorium responded in kind — engaging in a thoughtful two-hour presentation on the dangers of Islamophobia.

"It gave me goosebumps every so often," said Eric Lin, a Cal Poly junior math major who said he is not Muslim.

Lin said he was deeply touched by the single piece of advise Mogahed said she would offer to Muslim students and members of other often-persecuted minorities: "Never allow those who dislike you to define you."
